GPU Picker v0.2.0

What's in this release

• Fix: Legion Go / SteamOS showed Phoenix1 (lspci fallback) instead of the Vulkan device.
  Root cause: the Decky Loader is a PyInstaller bundle whose dir sits in LD_LIBRARY_PATH
  and ships its own libstdc++/libz/libffi — the radeon ICD's dependencies resolved
  to those copies → VK_ERROR_INCOMPATIBLE_DRIVER → 0 devices. Fixed with a clean-env
  subprocess fallback for Vulkan enumeration (verified on the device).
• Diagnostics now written to the first writable location (~/.gpu_diag.txt, /tmp/gpu_diag.txt)
  • backend log, instead of a root-owned plugin dir that silently swallowed errors.
• plugin.json now declares an explicit version (0.2.0).
